[0033] The driving unit 32 comprises an electric motor, a reduction gear box 321, a shaft sleeve 322 and a shaft rod 323 arranged in sequence from bottom to top along the axial direction of the shell 2. The electric motor and the reduction gear box 321 constitute a reduction motor, which is a common prior art and will not be described in detail.

[0034] The output shaft of the reduction gear box 321 faces upward, and a threaded blind hole is drilled at the top end of the output shaft. A rim 324 is arranged at the top end of the shell of the reduction gear box 321 along the edge. The shaft sleeve 322 has an inverted "T" structure, comprising a cylinder and a pad arranged at the bottom end of the cylinder, and the two are integrally connected. A relatively thick through hole is arranged at the center of the cylinder, and an axial spline groove is arranged in the through hole; a relatively thin through hole is arranged at the center of the pad.

[0035] During installation, a plane bearing is placed in the area between the top end of the reduction gear box 321, the rim 324 and the output shaft, and the thickness of the plane bearing is equal to the length of the output shaft extending out of the reduction gear box 321.

The sum of the thickness of the plane bearing and the pad is equal to the height of the rim 324, and the diameter of the pad is slightly smaller than the inner diameter of the rim 324.

[0036] Then, a screw is inserted into the through hole of the pad of the shaft sleeve 322 from the through hole of the cylinder of the shaft sleeve 322, and is screwed into the blind hole of the output shaft. Thus, the pad of the shaft sleeve 322, the plane bearing and the shell of the reduction gear box 321 are all locked and fixed.

[0037] ​In this structure, the shaft sleeve 322 rotates synchronously under the drive of the output shaft of the reduction gear box 321, and the lower surface of the base plate of the shaft sleeve 322 is supported by a plane bearing, and the outer side of the base plate is supported by the retaining edge 324, thereby ensuring the connection strength.

[0039] The lower end of the shaft rod 323 is inserted into the upper end of the cylinder of the shaft sleeve 322, and the spline of the shaft rod 323 engages with the spline of the cylinder of the shaft sleeve 322, that is, the shaft rod 323 can slide up and down in the cylinder of the shaft sleeve 322, and can also rotate synchronously with the shaft sleeve 322.

[0040] The manual opening and closing assembly 5 comprises a press handle switch 51, a transition connecting rod 52, a press handle connecting rod 53 and a reset spring 54.

[0041] The upper end of the press handle switch 51 is hinged to the top protrusion on the left side of the upper half of the shell 2, the lower end is pressed by the user, and the middle part is provided with a hinge point on one side of the shell 2.

[0042] The right end of the press handle connecting rod 53 is a circular gasket, which is sleeved on the shaft rod 323 outside the position above the protrusion. The inner side of the circular gasket is in clearance fit with the shaft rod 323, and a plane bearing is further sleeved between the lower surface of the circular gasket and the protrusion of the shaft rod 323. When the shaft rod 323 rotates, the press handle connecting rod 53 can remain relatively stationary.

[0043] The transition connecting rod 52 extends downward, leftward and downward again in sequence on the left side of the circular gasket of the press handle connecting rod 53, and is provided with a hinge point on the left side of the lowermost end. The two ends of the transition connecting rod 52 are respectively hinged to the hinge points arranged on the press handle switch 51 and the press handle connecting rod 53.

[0044] A 2mm deep recess extending upward and downward is arranged on the upper position of the inner wall on the left side of the upper half of the shell 2, and a 2mm deep recess extending upward and downward is arranged on the lower position of the outer wall on the left side, and the overlapping part between the two recesses constitutes a 1mm deep channel. The lengths of the two recesses are basically the same, and the length is the stroke of the upward and downward movement of the press handle connecting rod 53.

[0045] The left end of the leftward and downward part of the press handle connecting rod 53 moves upward and downward in the upper recess, the downward extending part structure passes through the channel and moves upward and downward therein, and the hinge point on the left side of the lowermost end moves upward and downward in the lower recess.

The reset spring 54 rotates synchronously with the shaft rod 323 and the shaft sleeve 322.

[0047] When the handle pressing switch 51 is pressed, the handle pressing switch 51 drives the handle pressing connecting rod 53 to move downwards through the transition connecting rod 52, so that the circular gasket at the right end of the handle pressing connecting rod 53 drives the shaft rod 323 to move downwards. When the handle pressing switch 51 is released, the reset spring 54 drives the shaft rod 323 to move upwards, thereby driving the handle pressing connecting rod 53 to move upwards, and driving the handle pressing switch 51 to open through the transition connecting rod 52.

[0048] Please refer to Figures 1-3 , Figure 5 and Figure 7 , Figure 1 is a perspective view of the portable twisted pair wire twisting device 1 provided by the utility model, Figure 2 is Figure 1 a perspective view after the shell 2 is removed; Figure 3 is a partial sectional view formed by only cutting the shell 2 and the reduction gear box in the portable twisted pair wire twisting device 1 provided by the utility model, Figure 5 is Figure 3 a local enlarged view of the position of the clamping assembly 4, Figure 7 is an exploded view of the clamping assembly 4.

[0049] The clamping assembly 4 comprises, from bottom to top along the axial direction of the shell 2, a clamping gasket 41, a clamping arm base 42 and a clamping arm 43.

[0050] The clamping gasket 41 is a circular gasket, which is arranged on the upper surface of the boss 22 in the opening at the upper end of the shell 2, and is fixed in the shell 2 in an interference fit with the inner wall of the shell 2. A plane bearing is arranged on the upper surface of the clamping gasket 41.

[0051] The clamping arm base 42 is a circular base, which is downwardly protruded in the middle and sequentially passes through the center of the plane bearing and the clamping gasket 41 to the lower side of the clamping gasket 41. The clamping arm base 42 is in clearance fit with the inner wall of the shell 2 and can slide relative to the shell 2. The center of the clamping arm base 42 is provided with a through hole, and an axial spline groove is arranged on the inner wall of the through hole.

[0052] The shaft rod 323 passes through the through hole in the center of the clamping arm base 42, and the spline of the shaft rod 323 is engaged with the spline in the inner wall of the through hole of the clamping arm base 42. That is, the shaft rod 323 can slide up and down in the clamping arm base 42 and can also drive the clamping arm base 42 to rotate synchronously.

[0053] The upper surface of the clamping arm base 42 is provided with two hinge points. The structure of the clamping arm 43 is similar to the head of the commonly used clamp for untwisting the twisted pair wire.

[0054] The two clamping arms 43 are respectively hinged to the top end of the shaft 323 through a connecting rod at the middle part of the proximal side. A tooth groove is arranged at the top of the proximal side to increase the friction. With the up-and-down movement of the shaft 323, the two clamping arms 43 are driven to open and close through the connecting rod.

[0055] The two hinge points on the clamping arm base 42 are arranged at a position slightly close to the middle of the upper surface of the clamping arm base 42, so that a small gap is left at the edge of the clamping arm base 42. An arc-shaped groove is arranged on the inner wall of the upper end opening of the shell 2 at a position above the clamping arm base 42. A circlip 44 is arranged in the area above the clamping arm base 42 between the two hinge points and the inner wall of the shell 2, and is clamped in the arc-shaped groove of the inner wall of the shell 2. The circlip 44 provides a limiting function for the clamping arm base 42 to prevent the clamping arm base 42 from coming out.

[0056] As can be seen in Figure 7 , two sharp ends for clamping are arranged at the left opening position of the circlip 44. Correspondingly, a through hole for accommodating the sharp end is arranged on the shell 2 at a position above the protrusion for installing the push-button switch 51.

[0058] In use, the lower half of the shell 2 is held by hand, the end of the twisted pair wire to be twisted is arranged between the tooth grooves of the two clamping arms 43, the index finger and the middle finger press the push plate switch 51, the push-button connecting rod 53 is driven to move downwards through the transition connecting rod 52, the circular gasket at the right end of the push-button connecting rod 53 drives the shaft 323 to move downwards, and the return spring 54 is compressed at the same time.

[0059] With the downward movement of the shaft 323, the top end of the shaft 323 drives the two clamping arms 43 to close through the connecting rod, and the tooth grooves of the two clamping arms 43 clamp and fix the twisted pair wire.

[0060] Then the thumb presses the self-resetting button switch 34 to start the electric motor, and then the transmission of the reduction gear box 321, the shaft sleeve 322 and the shaft 323 drives the clamping arm base 42 and the two clamping arms 43 to rotate synchronously, and drives the twisted pair wire to rotate synchronously.

[0061] At the same time, the rotation speed of the electric motor and the rotation speed of the twisted pair are controlled by adjusting the pressing force of the thumb, and the twisted pair can be untwisted and straightened by the other hand at a suitable speed.

[0062] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
